Error codeF0
ApplianceCooktop
Quick answer
F0 means communications between the main and sub PCBs failed. Restart with POWER, then disconnect power for over 30 seconds.
Model compatibility: Dacor reuses codes across series and model years, so F0 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
F0 means communications between the main and sub PCBs failed.
What F0 tells you
F0 is the cooktop’s way of saying the main PCB and the sub PCB lost communication. You will see it on the Modernist induction cooktops DTI30M977BB and DTI36M977BB.
The manual’s order of steps
Restart the cooktop using the POWER button.
If F0 continues, disconnect power for more than 30 seconds.
Restart the cooktop again.
If the issue is not resolved, contact a Dacor service center.
A stubborn F0 is a reason to call (310) 742-1907 for cooktop repair in Los Angeles. Tell the team the code, your model number and that you already restarted twice.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
